Why is lockout/tagout essential before working on limited-energy cabling?

• A. To prevent energizing the circuit and protect workers from shock or unintended operation.
• B. To improve labeling accuracy for maintenance teams.
• C. To verify the circuit is energized for testing.
• D. To reduce the time required to perform maintenance.

Answer: (A)

Lockout/tagout is about keeping hazardous energy from being released while someone is working on electrical or limited-energy cabling. By locking the energy source in the off position and tagging it with information about who applied it, you prevent anyone from re-energizing the circuit accidentally. This directly protects workers from shock, unintended operation, or movement of the equipment during the service or installation. Other options don’t fit as the primary purpose. Labeling helps communication, but it doesn’t actively prevent energizing. Verifying that a circuit is energized is the opposite of what you do when performing lockout/tagout; the goal is to ensure zero energy before work. And while safety steps can add time upfront, the purpose of lockout/tagout is not to speed things up but to ensure a safe, controlled work environment.
